Jellyfish have provided insight into important components of animal propulsion, such as suction thrust, passive energy recapture, vortex wall effects, and the rotational mechanics of turning. These traits are critically important to jellyfish because they must propel themselves despite severe limitations on force production imposed by rudimentary cnidarian muscular structures. Consequently, jellyfish swimming can occur only by careful orchestration of fluid interactions. Yet these mechanics may be more broadly instructive because they also characterize processes shared with other animal swimmers, whose structural and neurological complexity can obscure these interactions. In comparison with other animal models, the structural simplicity, comparative energetic efficiency, and ease of use in laboratory experimentation allow jellyfish to serve as favorable test subjects for exploration of the hydrodynamic bases of animal propulsion. These same attributes also make jellyfish valuable models for insight into biomimetic or bioinspired engineeringof swimming vehicles. Here, we review advances in understanding of propulsive mechanics derived from jellyfish models as a pathway toward the application of animal mechanics to vehicle designs.

水母游泳的水动力。

水母为动物推进的重要组成部分提供了洞察力,例如吸力,被动能量捕获,涡流壁效应以及转向的旋转机制。这些特征对于水母至关重要,因为尽管基本的刺胞肌肉结构会严重限制力量产生,但它们必须自我推动。因此,只能通过精心安排流体相互作用来进行水母游泳。然而,这些机制可能具有更广泛的指导意义,因为它们还表征了与其他动物游泳者共享的过程,这些动物的结构和神经学复杂性会掩盖这些相互作用。与其他动物模型相比,其结构简单,相对的能量效率,实验室实验的便利性和易用性使水母成为探索动物推进的水动力基础的良好测试对象。这些相同的属性也使水母成为了解游泳车辆仿生或生物启发工程学的有价值的模型。在这里,我们回顾了对从水母模型得出的推进力学的理解的进展,这是将动物力学应用于车辆设计的一种途径。
